Package name kernel
Date April 17th, 2006
Advisory ID MDKSA-2006:072
Affected versions CS3.0, MNF2.0
Synopsis Updated kernel packages fix multiple vulnerabilities

Problem Description

A number of vulnerabilities were discovered and corrected in the Linux
2.6 kernel:

Prior to Linux kernel 2.6.5, a numeric casting discrepancy in sdla_xfer
allowed local users to read portions of kernel memory (CVE-2004-2607).

Prior to 2.6.12, multiple "range checking flaws" in ISO9660 filesystem
handler could allow attackers to cause a DoS or corrupt memory via a
crafted filesystem (CVE-2005-0815).

Prior to 2.6.14-rc5, when running IPv6, the udp_v6_get_port function
allowed local users to cause a DoS (infinite loop and crash)

A race condition when threads are sharing memory mapping via CLONE_VM
could allow local users to cause a DoS (deadlock) by triggering a core
dump (CVE-2005-3106).

When one thread is tracing another thread that shares the same memory
map, could allow local users to cause a DoS (deadlock) by forcing a
core dump (CVE-2005-3107).

A race condition in the ebtables netfilter module, when running on an
SMP system under heavy load, might allow remote attackers to cause a
DoS (crash) via series of packets that cause a value to be modified
after if has been read but before it has been locked (CVE-2005-3110).

Prior to, the ptrace functionality, using CLONE_THREAD, does
not use the thread group ID to check whether it is attaching to itself,
allowing local users to cause a DoS (crash) (CVE-2005-3783).

Prior to 2.6.14, the IPv6 flow label handling code modified the wrong
variable in certain circumstances, which allowed local user to corrupt
kernel memory or cause a DoS (crash) by triggering a free of non-
allocated memory (CVE-2005-3806).

Prior to and 2.6.13, a memory leak in the icmp_push_reply
function allowed remote attackers to cause a DoS (memory consumption)
via a large number of crafted packets (CVE-2005-3848).

Prior to 2.6.15-rc3, the time_out_leases function allowed local users
to cause a DoS (kernel log message consumption) by causing a large
number of broken leases, which is recorded to the log using the printk
function (CVE-2005-3857).

In addition to these security fixes, other fixes have been included
such as:

- fix nfs blocksize setting (bk tree)
- update sata_sil to 0.9
- update ndiswrapper to 1.0
- update 3w-9xxx to (9550SX support)
- update tg3 "ng" (3.6)
- add support for ATI IXP400 audio (alsa) and ide
- add support for new sata_sil chipset for RS480 platforms (NEC)
- add support for MCP51 IDE & NIC (nForce 430)
- various x86_64 fixes from newer kernels
- sata_nv: support for MCP51
- piix: ICH7 support
- add netcell and piccolo support
- updated e100 and e1000 drivers from 2006
- updated aic79xx

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.
